We study the Besov regularity of conformal mappings for domains with rough boundary based on the well-posedness for the Dirichlet problem with Besov data.
The proposed rough-fuzzy QFD system combines fuzzy arithmetic operations with the two novel concepts of rough number and rough boundary interval that are derived from rough set theory.

Predictive errors, however, can be significant and further research is needed to better understand the physics of flow over rough boundaries and to incorporate this understanding in improved models of flow resistance.
For one victim, nearly 200 pieces have been identified, while for others, there was a single shard of bone. 1 Attack Fund Coming Into Focus Kenneth R.
